		Values
	voIpProt.server.x.address	dotted-decimal	Null	IP address or host name and
		IP address or		port of a SIP server that accepts
		host name		registrations. Multiple servers
				can be listed starting with x=1,
	voIpProt.server.x.port	0, Null, 1 to	Null
				2, ... for fault tolerance.
		65535
				If port is 0 or Null:
				If voIpProt.server.x.address is a
				hostname and voIp-
				Prot.server.x.transport is set to
				DNSnaptr, do NAPTR then
				SRV lookups.
				If voIpProt.server.x.transport is
				set to TCPpreferred or
				UDPonly then use 5060 and
				don’t advertise the port number
				in signalling.
				If voIpProt.server.x.address is
				an IP address, there is no DNS
				lookup and 5060 is used for the
				port but it is not advertised in
				signaling.
				If port is 1 to 65535:
				This value is used and it is
				advertised in signaling.
	voIpProt.server.x.transport	DNSnaptr or	DNSna	If set to Null or DNSnaptr:
		TCPpreferred or	ptr	If voIpProt.server.x.address is a
		UDPonly		hostname and voIp-
				Prot.server.x.port is 0 or Null,
				do NAPTR then SRV look-ups
				to try to discover the transport,
				ports and servers, as per RFC
				3263. If voIp-
				Prot.server.x.address is an IP
				address, or a port is given, then
				UDP is used.
				If set to TCPpreferred:
				TCP is the preferred transport,
				UDP is used if TCP fails.
				If set to UDPonly:
				Only UDP will be used.
	voIpProt.server.x.expires	positive integer,	3600	Requested registration period
		minimum 300		in secondsa.
